Even though Likes, Tweets, +1 and Shares do not really influence the search engine optimization at the current time, it can be assumed that this will change in the future. However, there is often only a correlation between sites with good rankings and a high number of followers in social networks.

Basically, it is always good to offer visitors to a website, to like or share content. On the one hand, this is a possibility for the user to interact with the website (which is seen by Google), and on the other hand, the range of a blog contribution can be enormously increased.

Furthermore, it is also possible that a user who has seen a social recommendation will publish it on a website, which will give you a link to your website.
